For thou, O God, hast proved us: thou hast tried us, as silver is tried.
The psalmist celebrates one deliverance, but means it as proof of God's constant mercy to His people through all ages. His point is comfort: our subjection to enemies has been the furnace proving us as silver, and God's hearing of the faithful proves His acceptance of them alone, not the wicked.

Commenting on Psalm 66:1-20
For thou, O God, hast proved us. He proved his Israel with sore trials. David had his temptations. All the saints must go to the proving house; God had one Son without sin, but he never had a son without trial. Why ought we to complain if we are subjected to the rule which is common to all the family, and from which so much benefit has flowed to them?
In these verses the psalmist calls upon God's people in a special manner to praise him. Let all lands do it, but Israel's land particularly. Bless our God; bless him as ours, a God in covenant with us, and that takes care of us as his own.
